Honey bee bgm download9/17/2023 Some of the DEGs are either known to be methylated or are implicated in epigenetic processes suggesting that responses to light exposure are at least partly regulated at the epigenome level. Most of the DEGs show age‐related changes in the amplitude of light‐induced expression and are likely to be both developmentally and environmentally regulated. We have found a number of differentially expressed genes ( DEGs), both novel and conserved, including several genes with reported roles in neuronal plasticity. We have compared gene expression in brain compartments of 1‐ and 7‐day‐old light‐exposed honey bees with age‐matched dark‐kept individuals. ![]() Here, we extended these analyses to the molecular level to unravel light‐induced transcriptomic and epigenomic changes in the honey bee brain. Our previous work has shown that light exposure induces structural neuronal plasticity in the mushroom bodies ( MBs), a brain center implicated in processing inputs from sensory modalities. Light is a powerful environmental stimulus of special importance in social honey bees that undergo a behavioral transition from in‐hive to outdoor foraging duties.
